Answer to Question 1

ANS: D

Feedback
A Some descriptive studies may have one variable only, and qualitative studies do not include independent and dependent variables.
B Many studies include more than one independent variable and more than one dependent variable.
C The relationship between independent and dependent variables is not necessarily causal. An association between variables need not indicate causality.
D Depending on the particular study, a specific variable may be the dependent or the independent variable. The causal or associative direction between variables determines the classification of the variables as independent or dependent.

Answer to Question 2

ANS: A

Feedback
A Infant health is the consequence or presumed effect that changes regarding maternal employment. Thus it is the dependent variable.
B Maternal employment is presumed to effect a change in the infant's behavior (the dependent variable). Thus, maternal employment is the independent variable.
C The first 6 months of life refers to the time the subjects (mothers and infants) will be observed in the study.
D Health care professionals constitute the population to be studied.
